Lauren had 3 liters of water. She poured the water into 7 glasses equally. How much water was there in each glass

Question

 this is a math problem and I don't know how to do it

Answer 1

"...3 liters of water ... poured the water into 7 glasses equally"

    3 liters           divided by                        7 glasses

     (3 liters)          per                               (7 glasses)

     (3 liters)  / (7 glasses)

     3/7 liters/glass

     3/7 liters per glass

Answer 2

Each of the 7 glasses received 1/7 of the water

3(1/7) = 3/7 of a liter per glass
